"Google is developing a new kind of search capability that delivers the results instantly as you type the letters.

The new experiment was discovered by search engine optimization (SEO) consultant Rob Ousbey, who noticed the results being delivered instantly and then recorded a video to show it. Google confirmed to TechCrunch
that the video is real. It will be interesting to see if the new
capability is launched as a standard part of Google’s search engine. It
could save us all time as we type familiar searches where we know that
the instantly-delivered search result is most likely the one we want to
click on."
